With this fundamental constitution, civilization had accomplished things for which the old gentile society was no match whatever. But these exploits were accomplished by playing on the most sordid passions and instincts of man, and by developing them at the expense of all his other gifts. Barefaced covetousness was the moving spirit of civilization from its first dawn to the present day; wealth, and again wealth, and for the third time wealth; wealth, not of society, but of the puny individual, was its only and final aim. If nevertheless the advanced development of science, and at repeated times the highest flower of art, fell into its lap, this was only due to the fact that without them the highest emoluments of modern wealth would have been missing. Exploitation of one class by another being the basis of civilization, its whole development involves a continual contradiction. Every progress of production is at the same time a retrogression in the condition of the oppressed class, that is of the great majority. Every benefit for one class is necessarily an evil for the other, every new emancipation of one class a new oppression for the other. The most drastic proof of this is furnished by the introduction of machinery, the effects of which are well known to-day. And while there is hardly any distinction between rights and duties among barbarians, as we have seen, civilization makes the difference between these two plain even to the dullest mind. For now one class has nearly all the rights, the other class nearly all the duties. But this is not admitted. What is good for the ruling class, is alleged to be good for the whole of society with which the ruling class identifies itself. The more civilization advances, the more it is found to cover with the cloak of charity the evils necessarily created by it, to excuse them or to deny their existence, in short to introduce a conventional hypocrisy that culminates in the declaration: The exploitation of the oppressed class is carried on by the exploiting class solely in the interest of the exploited class itself. And if the latter does not recognize this, but even becomes rebellious, it is simply the worst ingratitude to its benefactors, the exploiters.[46] And now, in conclusion, let me add Morgan's judgment of civilization (Ancient Society, page 552):
